An ALS patient set a record for communicating via a brain implant: 62 words per minute

MIT Technology Review

The new research was carried out at Stanford University. The preprint, published January 21, began drawing extra attention on Twitter and other social media because of the death this week of its co-lead author, Krishna Shenoy, from pancreatic cancer. Shenoy had devoted his career to improving the speed of communication through brain interfaces, carefully maintaining a list of records on his laboratory website. In 2019, another volunteer Shenoy worked with managed to use his thoughts to type at a rate of 18 words a minute, a record performance at the time, as we related in MIT Technology Review's special issue on computing. The brain-computer interfaces that Shenoy's team works with involve a small pad of sharp electrodes embedded in a person's motor cortex, the brain region most involved in movement.


A Virtual Social Life Is Possible with Brain-Machine Interfaces

WIRED

A major goal of the field of neuroprosthetics has focused on improving the lives of paralyzed patients by restoring their lost real-world abilities. This story is from the WIRED World in 2023, our annual trends briefing. Read more stories from the series here--or download or order a copy of the magazine. One example was the 2012 work by neuroscientists Leigh Hochberg and John Donoghue at Brown University. Their team trained two people with long-standing paralysis--a 58-year-old woman and a 66-year-old man--to use a brain-machine interface (BMI) which decoded signals from their motor cortex to direct a robotic arm to reach for and grasp objects.


First implant to treat depression is REVEALED: New brain chip set to rival Elon Musk's Nueralink

Daily Mail - Science & tech

While Elon Musk's Neuralink expects to begin human trials in six months, a neurotech company unveiled a device that treats depression and is now in the skull of the first patient. Inner Cosmos's'digital pill' includes two parts: An electrode that sits under the skin of the scalp and the'prescription pod' that snaps onto the users' hair to power the device. The implant sends tiny electrical pulses to the brain region affected by depression - the left dorsolateral prefrontal cortex - once daily for 15 minutes. And the external device does not need to be on the head when treatment is not being administered. The trial patient from St Louise, Missouri, is scheduled to test Inner Cosmos innovation for one year, and the company has another human trial set to start next month.


Do you understand how AI can revolutionize your marketing? - I by IMD

#artificialintelligence

AI is a hot commodity in the marketing space – but like all new tools, many companies adopting it don't fully understand its benefits and its drawbacks. As a result, most marketers are using AI in an ad hoc manner, lacking in a clear strategy. To really gain a competitive advantage, executives need to rethink the scope and framing of how they are viewing AI and shift from improving on traditional and familiar marketing strategies to considering game-changing new ideas. For today's exercise, consider these questions and ask yourself where AI could assist in making critical strategic decisions. As a marketer, how are you looking for new markets or product segments?


What does the future hold for brain implant technology?

Al Jazeera

On Wednesday, December 14 at 19:30 GMT: For decades, scientists have been developing brain-computer interfaces – technology that allows humans to control computers via the power of thought alone. Researchers have found some success in using BCI technology with brain implants that help people with mobility disorders control prosthetic limbs. In other research settings, implanted microchips have also been used to help people with disabilities or neuromuscular diseases manage seizures and communicate through text messages. Now private companies like Elon Musk's Neuralink are growing their presence in the neurotech field, and with that growth comes the prospect of creating brain implant devices for a broader market beyond those with disabilities. The neurotech company Synchron is currently testing a surgically implanted device that allows a person to control an iPhone using only thoughts.


How does Elon Musk's Neuralink brain chip actually work?

Daily Mail - Science & tech

For the past six years, Elon Musk has been working on a chip designed to be implanted into human brains, with his neurotechnology company Neuralink. His ultimate goal is to develop a'brain-computer interface' that will initially be used to help people with paralysis or motor neurone disease to communicate. It will allegedly allow them to operate computers and mobile devices using their thoughts, but could have further uses in years to come. So what exactly is the chip? How does it work and how will it cure all medical problems?


Musk says brain chip to begin human trials soon – and plans to get one himself

The Guardian

Elon Musk said on Wednesday he expects a brain chip developed by his health tech company to begin human trials in the next six months. During a presentation by Musk's company Neuralink, Musk gave updates on the company's wireless brain chip. In addition to forecasting clinical trials, Musk said he plans to get one of the chips himself. "We want to be extremely careful and certain that it will work well before putting a device into a human," said Musk, according to Reuters. Neuralink says it is developing brain-chip interfaces that could restore a person's vision, even in those who were born blind, and restore "full body functionality", including movement and verbal communication, for people with severed spinal cords, reported CNBC.


Elon Musk's Neuralink to share progress of its brain chip tonight

Daily Mail - Science & tech

Elon Musk's Neuralink is set to host its annual'Show and Tell' event tonight at 9 pm ET that is expected to share a progress update on its brain-machine interface. The neuroscience startup shared a teaser for the event on its Twitter account, showing a short video that spelled out the message'please join us for a show and tell,' and some users speculate the world will see a person with Neurlink's chip type on a screen. The goal is to develop a full-implanted brain-computer interface (BCI) for people with paralysis, allowing them to operate computers and mobile devices using their thoughts. The first Show and Tell event, held in 2020, demonstrated the technology with a pig and last year, Musk revealed the update with a monkey that played a video game using only its mind. Neuralink will host its annual'Show and Tell' event tonight at 9 pm ET, which is expected to share the progress of the technology.


Elon Musk's Neuralink has been 'mutilating and killing monkeys'

Daily Mail - Science & tech

Elon Musk plans to hold a'Show and Tell' event for his brain chip company Neuralink on November 30, but a group of physicians claims the firm is'mutilating and killing monkeys' to create a'brain-machine interface.' Musk announced the event, which the company holds each year to showcase its latest updates, on Twitter. The first Show and Tell in 2020 demonstrated the brain implant in a pig and in 2021, the world saw it used by a monkey that died months after receiving the implant. The Physicians Committee for Responsible Medicine (PCRM) recently launched a website detailing the gruesome stories of monkeys that are said to have suffered from sloppy experiments conducted at the University of California, Davis (UC Davis). PCRM shared lab notes with DailyMail.com


Brain mapping in mice may explain why pain makes us lose our appetite

New Scientist

The link between chronic pain and a loss of appetite may finally be understood – in mice at least. Zhi Zhang at the University of Science and Technology of China in Hefei and his colleagues injected mice with bacteria that provoke chronic pain. Ten days later, these mice were eating less frequently and for shorter periods of time compared with control mice that had been injected with saline. When the first group of mice were later given pain medication, they ate normally, the researchers wrote in a paper published in Nature Metabolism. To better understand the neuronal activity responsible for this change in behaviour, the researchers analysed the brains of the first group of mice while the animals were in chronic pain.
